Described is related to a nano-structured composite absorber for air detoxing and deodoring at ambient temperature to prevent harmful chemicals in the air from damaging human health. The nano-structured composite absorber consists of nano-porous carbon, zeolites with nano-sized pores and at least 1 other component chosen from nano-porous rare earth oxides and nano-sized catalysts. The synergetic action of those nano-structured components can effectively remove toxic chemicals including, but not limited to formaldehyde, benzene, toluene, xylene, propene, butadiene, acetone, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, ammonia, alcohols, chlorine, mercaptans, as well as malodors, such cigarette smoke, net/fish/poultry odors and bathroom/toilet smells.
A nano-structured composite absorber for removing toxic chemical pollutants and malodors from air at ambient temperature comprising nano-porous carbon and zeolites with nano-sized pores and at least 1 component selected from the group consisting of nano-porous rare earth oxides and nano-sized catalysts.
A nano-structured composite absorber comprising a body of honeycomb monolith with multiple parallel air flow through channels, or a monolith foam with tortuous air flow through channels, or multi-stacked bodies of honeycomb monolith, or multi-stacked bodies of monolith foam, or combinations thereof, wherein said monolith has nano porous carbon integrated intimately with other components including zeolite, nano-porous rare earth oxides, and/or nano-sized catalysts, and/or nano-sized catalysts supported on nano-porous rare earth oxides, and filler materials.
